If I have had contact with someone who’s been to an epidemic-affected area and my nucleic acid test result is negative, should I undergo quarantine? 06-15
Chinese Center for Disease Control and Prevention: According to current epidemiological investigations and research findings, the COVID-19 incubation period ranges from 1 to 14 days, and confirmed cases usually have an incubation period from 3 to 7 days. If the person you had contact with has ruled out COVID-19 infection, you don’t need to be quarantined. If the person is infected, but you took preventative measures during your contact with him or her and your nucleic acid test result is negative, then you don’t need to be quarantined. However, if you didn’t take preventative measures while you had contact with the person, even if your test result is negative, you’ll have to undergo a 14-day collective quarantine according to related policies.
